If you have more than one AP, a hotspot gateway is the recommended solution (it can be a Ubiquiti EdgeRouter or a Mikrotik hEX or any other Mikrotik router with RouterOS license level 4 or higher), then any AP can be used: you just have to connect them to that gateway. This way you can use the special features of the AP, you still have flexibility to expand your hotspot coverage, and the actual hotspot service runs on a central device.
